The 30% more refers to the original cost estimate. The reason why it is being picked on so much is that SLS has been advertised as being cheap to develop and launch due to it reusing preexisting parts. Yet it's total cost is approaching what NASA gets per year.

[Anonymous No.12058559]

When speaking of colonizing Venus's upper atmosphere with floating cities, how would you refine rocket propellant directly from Venus's atmosphere?

I'm asking this because virtually all discussions related to colonizing Venus ignore the biggest hurdle of them all. Not the heat, pressure or acid, but the massive delta v requirements for a return trip to Earth, simply because Venus's gravity is almost as strong as Earth's and we need fuckhuge launch systems to get ANYTHING into orbit from here. Now try doing that from a floating balloon station 30 miles above the surface where one slip-up can send you tumbling down into a sulfurous inferno, and you see where the problem arises.

Venus's atmosphere is mostly CO2 with traces of SO2 and H2SO4 vapor. If we can refine methlox or even RP1 from that we might be all set. Maybe you can just lower a long-ass air hose that reaches almost all the way down to the surface where air pumps suck it up to the floating station for refinement?

As far as strapping it to a booster stage, no, it wouldn't be worth it. Much like a rocket motor, the SR-72 needs fuel to propel itself. Instead of adding extra weight for an extra thrust system, it would be more efficient to bolt extra propellant tanks on the booster so the first stage could just burn longer/harder.

>"Salads" is a huge blanket word, and most salads these days are little nutrition

Venus' atmosphere is very very dry, and water is a vital resource for any ISRU propellant effort, because it's the simplest and easiest natural hydrogen-bearing compound to deal with when trying to run combustion reactions the wrong way. You could possibly use H2SO4 as your hydrogen source, but uuuh, I don't exactly know how. Maybe if you start off by making carbon monoxide you can react it with the H2SO4 to pull the hydrogens off? I have no idea. I do get the feeling though that any machine you try to build that is trying to decompose concentrated sulfuric acid into sulfur dioxide and hydrogen-bearing compounds is going to have corrosion issues.

As other anons have stated, Venus is a shit anyway, and we really shouldn't bother fucking around with it at all until we're at the point that we can use orbital ring mega-structures to extract resources from the planet while we all live inside habitats either suspended from those orbital rings or free-floating in Venusian orbits themselves. In fact Venus will likely become an economic powerhouse in the solar system simply because settling it in any permanent or large scale fashion won't be practical until long after we're already at the point of saying "fuck it, habitat swarms", which means it may be the biggest pile of resources around that will be free to just be strip mined down to nothing (even Mercury could be settled and transformed into a home for billions, living in large complexes underground and huge surface habitats at the poles/under sunshade canopies).

Nah, airbreathing jets lose power way too quickly as they ascend, and they don't have very good power to weight to begin with.
If you REALLY need to strap anything to a rocket, it needs to be another rocket, and if you have a brain it will also be a reusable rocket. Remember, Isp only matters if you're trying to get more delta V out of a single stage. If yo're adding more stages, you've already given up pushing for Isp, so you may as well go for the most practical and cheap options you can, as long as your total delta V still hits your minimum mission requirement. For example, getting 10km/s in one methalox stage is almost impossible, totally impractical. Getting 5km/s out of a methalox stage isn't even hard, you only need a propellant mass fraction of ~56%. Therefore, if you just use two methalox stages, you can easily achieve levels of performance that were totally out of reach of your propulsion technology using one stage.
Air breathing jet engines are really efficient compared to rocket engines, but you only need to add a single additional stage to your chemical rocket in order to put it far beyond the performance yo could possibly gain using an air breathing jet booster stage, and rocket stages are a hell of a lot easier than air breathing boosters.

I had a notion about decreasing Venus's atmospheric density long-term.
Imagine a satellite (really more a station with how big it would be) with a huge mylar scoop, collecting the rarefied upper atmosphere. It would use part of the gas collected to fuel an ion engine, and would orbit at the altitude where atmospheric drag more or less exactly counterbalanced the engine's continuous thrust. The rest of the gas- mostly CO2- would be turned into pellets of dry ice that the satellite would yeet into a higher orbit, or potentially even somewhere like SV-L2, with the hopes of creating an artificial dry ice asteroid/small moon.
A couple thousand of those might make a dent, given a few centuries.

Yes. They're setting up the facilities right now. Blue Origin stays quiet about its work as to not risk making a negative image of themselves. If you don't believe it, then remember that their engine (the BE-4) was chosen by ULA for their Vulcan rocket over Aerojet's engine. Meanwhile, SpaceX had to sue to get contracts for their Falcon 9 which as already proven itself at that point. It might now show well, but Blue Origin is clearly doing alot behind the scenes.

This, you really need something approaching torch ship territory (or reactionless wizard shit) to do better than Starship at Oberth-effect boost, and that means you need more dV for the same trip, and most nuclear designs are LH2 based which further cuts into the payload.

>>12059391
If you're doing literally anything other than two in-line stages, you either are not optimizing the thrust to weight ratio of your first stage (needing boosters to compensate) or you are oversizing your first stage and giving it boosters on purpose as a 'sustainer' (really just an upper stage with extra tankage).

Booster-sustainer is such an awful concept. Take Ariane 5 as an example; the solid boosters already provide ~90% of the liftoff thrust, the 'main engine' is not really helping at all. Later the boosters burn out and separate, and the center core continues to accelerate, but now it's already 30% drained of propellants. If Ariane 5 instead shortened the main stage tanks by 30%, and lit in mid air just before or after booster sep, that would lead DIRECTLY to a performance increase, because the stage would no longer be pushing as much dry mass and thus would have a better mass fraction and more delta V. In fact, they could also tweak the engine to be vacuum optimized, and since they don't need to make way for the middle engine's exhaust they could mount the solids directly underneath the hydrolox stage (simplifying the core's structure since it doesn't need to take side loads, which would also lighten it further), and while they're at it they could replace the two solids with either a bigger single solid or a liquid propellant stage, etc etc, you see where this is going.

Why is TSTO the optimal design choice? It's because it's harder than it's worth to try to get more than ~6 km/s of delta V out of a chemically propelled stage, and you only need two of those stages in order to have the >9.5 km/s of delta V necessary to achieve orbit around Earth. You would need to design your rocket wrong on purpose as a joke in order to require three stages to achieve Earth orbit (Saturn V doesn't count because it only needed a short burn of the third stage to reach orbit, and that third stage's real job was achieving trans-lunar injection).

>Also the space shuttle was like, basically a 2-staged horizontally stacked rocket
Shuttle is a booster-sustainer, literally the WORST rocket design before you even start to look at the other parts of Shuttle, such as the Orbiter itself.
If you are doing booster-sustainer, what you have actually done is split a first stage in half and wrap it around a second stage, then lengthen that second stage to the point that it would have much too low a thrust to weight ratio to be able to achieve orbit in time, which means the second stage now also needs to fire its engines during the early parts of the launch, which means it cannot use vacuum optimized engines and it won't have full propellant tanks by the time stage separation happens.
Do you know why booster-sustainer rockets were first invented? It's because back when the Atlas rockets and the R-7 rockets were the hot new thing, nobody was certain that engine ignition while flying would ever be reliable enough to count on. We're talking early 50's level of design constraints here.
Do you know why Shuttle was a booster-sustainer? It's because they wanted to recover the "expensive" parts, the engines, and throw away the "cheap" parts, like the $70 million external tank.
Do you know why SLS is a booster sustainer? It's because Congress didn't want to spend a lot of money (lol) developing a big kerosene first stage and redeveloping the RS-25 to be able to be lit in flight.
Do you know why Ariane 5 and 6 are booster sustainer? It's because frogs are fucking retarded.

[Anonymous No.12060137]

>>12060048
The Shuttle or Energia/Buran are actually justifiable booster/sustainer designs because the orbiter wings make putting it on top of a first stage impossible aerodynamically, so you have to hang it off the side of the main tank... but that orbiter design is itself a dead end.

Booster-sustainer might actually make sense for nuclear-thermal, since most designs have TWR under 1, and you don't ever want to drop giant fission reactors on people so they'll stay in orbit indefinitely. Slap on a fairing and a couple of SRBs and the "sustainer" stage can lift comfortably from Earth, and then you can catch the discarded parts on the way down for reuse launching more nuclear rockets. This has the advantage of not requiring orbital assembly or being diameter constrained by the payload bay of existing rockets. Then you can use Starship as an actual space shuttle, ferrying cargo and crew between planetary surfaces and the big nuclear spaceship.

Of course this doesn't work without orbital propellant depots, so unless we can pitch it as an "SLS-NT" evolution of the existing stack, Shelby will smother it in committee.

You could, but then you have to play orbital assembly fuck-fuck games and are volume limited by the payload bay of your chemical rocket. This is a major pain in the dick for nuclear reactors since scaling them down is way harder than scaling them up (especially for neutron shielding), and also ruins your propellant capacity since LH2 hates small tanks. This is the main reason why most "realistic" nuclear thermal Mars missions are so weaksauce. As for the RUD risk, the open ocean is a perfectly acceptable radiation sink.

I think it was the Shuttle and then everyone else cargo culting it. For the Shuttle it vaguely made sense because you wanted that hydrolox Isp for vacuum and stacked staging was impossible. Ariane and H-II were pretty clearly just aping the Shuttle, and the Delta IV uses the RS-68, a sibling of the SSME which inherits all the problems of the RS-25 while also being incapable of clustering due to the ablative nozzle.

I agreed with you at first, but after second thought, it doesn’t make sense. The hydrolox RD-25’s only carried it to orbit (presumably firing in the atmosphere most of the way). Once it was in space those engines were dead weight and it used to Hypergolic OMS to maneuver. Shuttle should have been RP-1. But yeah I agree that all other hydrolox rockets were probably just copying the shuttle. If America is putting in the R&D and doing it, it sets the standard across the globe apparently hahah

[Anonymous No.12061721]

Hello /sfg/, sort of a stupid question but I think I can phrase it constructively. I was thinking of the problem of taking off from the lunar surface (e.g. Apollo ascent stage) and going into lunar orbit, as opposed to the corresponding earth problem. The lunar problem would seem to be "easier" since the Moon has (effectively) zero atmosphere, removing multiple terms and considerations I bet.

The crux of my question is that I don't fully understand what it takes for an object/projectile to get away from a planetary body and enter orbit around that body, especially a body with effectively no atmosphere, in this case. I am familiar with the notion that spacecraft in Earth orbit are in "free fall" but there's little to no atmospheric drag bringing them down, until there is. Is there a certain minimum altitude in the Lunar case due to mascons, or am I simply describing "delta vee"? The latter is another thing I don't fully understand and I felt like asking before actually looking it up.

Terms I intuit:

-mass of planetary body
-mass of projectile to be put in orbit
-atmospheric drag/considerations
-desired orbital altitude

I should of course have added to this rotational considerations, but I really don't know anything about physics. I would expect anons to indicate things like the rocket equation, whatever that is exactly, and delta-vee, which I'll look up shortly, but I'm just curious about the lunar case and why it's different (the atmosphere being the big thing).

Atmospheric drag in low Earth orbit is gradual enough that you can counteract it with piddly little ion thrusters. Deliberate re-entry into the atmosphere at the correct angle (so you don't burn up or bounce off into space) is how you brake to slow down from 17,500mph across the ground to something your landing system can handle.

All it takes is the correct speed to enter orbit. It gets trickier when you have an atmosphere. For example, I could technically reach a speed to “orbit” the earth 2 meters above the ground... but the atmosphere fucks it all up. I could also orbit the Moon 2 meters above the ground, assuming a cliff doesn’t stop me. There are pretty simple equations for orbits. It’s all about solving for speed, depending on how far above the body you want to orbit

>Okay, this "orbital velocity of the body" bit is definitely a piece I was missing. What is the "orbital velocity of the (escaped) body" with reference to, exactly?

Here's a simple example: If you throw a rock forward, it will travel forward and eventually hit the ground little bit away. Throw the rock faster and it will travel farther but still hit the ground. Keep in mind the planet is curved. Throw the rock at a fast enough speed that it will fall but never hit the ground because it is continually falling around the curve of the planet.

The speed at which the rock moves parallel to the ground but never hits the ground is the "orbital velocity". Now if you throw that rock even faster than that, you will eventually reach "escape velocity" where it never comes back around.

2. Delayed their rocket launch 2 times on a row. The same rocket is in Cape Canaveral, where SpaceX is also scheduled to launch two rockets after ULA's rocket, and to set a new milestone: 2 launches on the same day. That may not happened due to ULA's rocket not launching.

no you don't just fly up and end up in orbit once you reach space
you fly up a bit untill you are out of the atmosphere and then you accelerate to orbital velocity. the absolute majority of the time the Shuttle engines were used in vacuum or near vacuum conditions. the OMS only did the last bit of circularization.

it'll drop them automatically if you have them in a stage by themselves and they are in the next stage when it's time to drop them

Simple. If you think the primary cause of climate change is something like methane escaping from melting tundric permafrost but to get that process started required the relatively smaller impact from human activity, human activity is the driving force that enabled the primary cause.
